uids; and it relates more particularly to the` construction andarrangement thereof.

The principal objects of my invention are first, to provide acomparatively simple, durable and efficient vapor burner; second, to

. provide a vapor-burner in Which the naphtha,

gasoline or other hydrocarbon uids are presented adjacent to the base ofthe burner to the generating chamber thereof, in order to expedite andinsurea better vaporization and t-o afford better illuminating effectsresulting from a given quantity of fluid utilized in the production of aflame at the exposed end of the burner in the presence of a mixing cham`ber; third, to provide a vapor burner with a laterally adjustable curveddetlector plate for spreading the ilame and with an air shield andmixing chamber connected therewith and located adjacent to a gasgenerating chamber and the naphtha, gasoline or other hydrocarbon iiuidintroduced into said chamber by means of controlled pipe connectionsfrom the front of the burner or hottest portion thereof, in order toenhance the character of vapor generated from the fiuid passingtherethrough, to reduce Waste and to increase the illuminatingproperties derived therefrom; fourth, to pro- `vide a vapor-burner inwhich the several conduits or channels leading to the chamber, theconstruction being such as to adapt the same to inside and outsidepurposes. y

Myinvention consists of the improvements in vapor-burners hereinafterdescribed and claimed.

The nature, scope and general features of my invention will be morefully understood from the following description taken in con- 6o nectionwith the accompanying drawings forming part hereof;` and in which-Figure l, is a perspective view of a vapor burner embodying features ofmy invention shown in application to a main provided with a globe-shapedWater trap and with means connected therewith -for regulating the supplyof fluids to the main and for permitting of the. discharge of water fromthe trap, the construction and arrangement of the appara- 7o tus thereinshown is such that the same is especially adapted for use in streetlamps. Fig.

2, is a View in perspective of the burner proper detached from the mainsupply pipe or connection; and Fig. 3, is a vertical longitudinalsection of avapor burner embodying features of my invention and adaptedfor the reception of a shade or globe for inside lighting purposes.

Referring to the drawings a, is a main sup- 8o ply pipe havingdetachably connected therewith a globe shaped Watertrap and fluidregulator B, provided with a stop-cock b', and with a blow-off valve orcook b2, having a cuto key b3. The section a', of the fluid supply 8 5pipe a, is adapted for the reception of a Wicking a2.

C, is the vapor-burner provided with an internal longitudinal channelc', and a vertical channel or conduit c2, leading directly to the 9ovaporizing or generating chamber o3, with an internally threaded valvestem socket c4, adapted for the' reception `of the threaded stem of theneedle pointed cock d, having a key d. The generating chamber c3, has acontracted vapor nozzle or exit c6, into the interior of which normallyengages the tapering end of the cock d. The generating chamber has adepending threaded extension c5, which is adapted for the reception ofthe roo threaded integral neck d2, of the cupshaped device d3, forcontaining hydrocarbon fluid or naphtha which is'permitted to escapethrough the contracted vapor nozzle c6, of the generating chamber c3,into the same, in order that by the igniting of the same`r by radiationthey generating chamberL may'g be heated up for vaporizing the fluidescaping or forced into said chamber. i Formed integral with the castingcomprising the parts of the burner is a curved bearing plate for thereception of a laterally adjustable curvedy fiame deilector plate c7,provided with Wind or air shields e and e2, bent in such manneras toform a hood and comprising a mixing chamber adjacent to the vapordischarge nozzlel of the generating chamber e3. 4Into one end of theconduits or channels of the casting constituting the burner C, isinserted athreaded plug f, for a f purpose to be presently fullydescribed.

With special 'reference to Fig. l, the flow of the naphtha or otherhydrocarbon Huid from a suitable supply is through fhepipe c,

and trap B, under` regulation, which is de-V `tachably connected Withthesectionof pipe y a', containinga wicking to the burner proper.`

Any kWater carried into the pipe d and trap B, by reason of its specificgravityfalls to the bottom of the trap B, and is discharged through thevalve b2, by opening the cock b3. The fluid or naphtha passing throughthe wicking or analogous ymaterial a2, and regulating the supply offluid to the generating or vaporizing chamber, passesina curveddirection through the `internal conduit c', of the burner proper andbyoperating'the needle-cock d,by means of its key d', the vapor generatedin the rst instance bythe heating up of the chamber c3, is ignited,producing a flame at the exposed yendfof. the contracted orifice c6, ofthe generating chamber c3." vThe vaporization of the fluid inthe firstinstance, is obtained by permitting the fluid to flow through thegenerating chamber and to escape through the contracted flame orificethereof in such manner as to drip into the cup-shaped device d3, when byigniting'the same the generating chamber c3, is heated up so as tohasten the vaporizing of `the Huid contained therein, and in order kthatby 4applying a ame thereto, the gas issuing from the exposed end of thecontracted orifice c6, of the generating chambercg, may be readilyignited. The pressure of the gas from the chamber c3, through itscontracted nozzle cl", is under control, so that the flame presented tothe detiector plate and mixing With the surrounding air may according torequirements be of greater or less intensity but of high illuminatingpower, by reason of the perfect vaporization obtained due to theparticular arrangement above explained of the several parts of theburner C. The extent, however, of the flame can be `regulatedy entirelyby the operation of the needle cock d, by means of its key d', asclearly shown in Figs. l and 3.

With reference to Fig. modified form of the burner such as is especiallyadapted for inside lighting purposes. In this instance the longitudinalconduit or r3, is shown a slightly f channel' ci, of theA casting C, isclosed by means'of a screw threaded plug f, and the ad-A mission of thefluidto the internaly gas genrection, through the nipple ,detachablyconnected with the T-coupling, vertical andjlongitudinal conduits'orchannels cgand c', to the generating chamber c3. Surrounding the nipple,'is asleeve i', for supporting to position a bracketj, provided withprojecting armsj',

adapted to receiveand holdto position a j y In the supplyr pipe a, ismounted suitable wicking or analo-V l;

globe `or shade, not shown.

gous material a2, for permitting to a greater kor less extentof theregulation of the Iiowjot the fluid therefrom to the T-coupling g,con-v` 'trolled 'as to the escape of Vfluidftherefromrto, H

the burner proper by means of the cockgf, by the turning of the `key g'2thereof. The

fluid in this device for'effect-ing vaporization in the first instance,is permitted by allowing f. a certain quantityof the same toy flowtherel ltliroughinto the generatingchamber andto n i j escapetherefromthrongh the contracted noz-` zle c6, by releasing the'needlecock whence lit drips therefrom into the cup-shaped device di',and by the ,application ot' a flame thereto it is ignited in such manneras that by radiationthe chamber c3, is heated, in or` der to vaporizethe fluid and continues under v due regulation of the tioW of uidthrough the parts of the burner to maintain the required ame at theexposed end of thecontracted orifice c6, of the 'generating chamber c3.

Oner of the main advantageous features of,

this device isL they presenting of the Huid to the burner forvaporizngthe same at the hottest portion thereof, in rorder toproduce' a flame atthe exposed end of the contracted nozzle of the generating chamber,whereby the uid is expeditiously vaporized` anda flame of greatintensity and high'illuminatingpower is obtained. Hitherto in the use ofvapor-burners, the fluid has generally been k 'f adjacent to theigniting point thereof, so that thesame may not only be thoroughlyvaporf ized, butthe greatest number of unitsA of efliciency obtainedthere from forlightingpuri poses. Moreover, the mixing of the air at thepoint of r`ignition of the issuing vapor from the generating chambergreatly enhances the such a burner.

t The burner of my invention possesses illuminating quality of the gasyproduced in f 4 by f kreason of itsconstructlon and arrangement thedesirable features requisite for the expeditious vaporization of theIiuid, the reduction of waste to aminimum and the obtaining of thegreatest illuminating eect without requiringan abnormal amount of heatin and about the generating chamber for the obtaining of the resultsmentioned. The deflector plate as clearly illustrated in Fig. 2, isprovided with an oblong slot f3, having a tightening screw f4, extendingtherethrough. This 'arrangement aords the means whereby the same may beset at an angle to the contracted iame orifice or Vapor discharge pipec6, in order to increase or lessen the area of the llame, which isdesirable in some instances should be under perfect regulation from anilluminating standpoint and more especially in house lighting Where aglobe or shade is employed in connection with a burner of the type, forexample, illustrated in Fig. 3.
